The hackers known as “Anonymous,” who helped organize and support the Occupy movement’s protests, have released an online a survivor guide for citizens “in case of a violent revolution in your country.”

The guide warns protests can be a “bloody mess.” It trains rioters on how to avoid tear gas, rubber bullets and live ammunition.

The 15-page PDF document claims police will not help protesters and may actually be enemies of the revolution while warning that protest groups may be infiltrated by “fake civilians.”

The Anonymous survival guide was published just before the hacker group claimed Sunday to have stolen thousands of credit card numbers and other personal information belonging to clients of U.S.-based security think tank Stratfor.
